Cambridge, United Kingdom - July 2, 2024

In a groundbreaking study published in Current Biology on July 2, researchers from the University of Cambridge and the University of East Anglia reveal that blue and great tits possess sophisticated memory capabilities akin to episodic memory, previously thought to be exclusive to humans. These wild birds were observed recalling past feeding experiences based on what, where, and when they found food, adapting their foraging behavior to changing conditions.

Using innovative techniques with automated food containers and RFID tracking tags, the researchers found that the birds exhibited "episodic-like" memory by remembering specific details of past feeding events. For instance, after learning the temporal rules of food availability, the tits adjusted their visits to feeders accordingly, showing an ability to distinguish between preferred and less preferred food types.

Dr. James Davies, lead author from the University of Cambridge, emphasized the significance of these findings: "This study provides the first evidence of episodic-like memory in wild birds, highlighting the flexibility and intelligence of blue and great tits in natural settings."

The research suggests that such memory abilities could aid these birds in coping with environmental changes and fluctuations, potentially influenced by factors like climate change. Moreover, the study proposes that human interventions, such as providing bird feeders in gardens, might inadvertently contribute to the evolution of these memory traits among urban bird populations.

Dr. Gabrielle Davidson from the University of East Anglia commented on the study's implications: "Observing these birds in their natural habitat allowed us to capture a realistic portrayal of their cognitive abilities. It's intriguing to see how they utilize memory to optimize foraging strategies."

This research underscores the broader understanding of animal cognition and memory across species, challenging traditional views of memory as a purely human trait.
